@roquegv please do not PR into version-14 without having it thorowly tested first. I advice to create a "develop" branch and do the testing there first. @reggaetuna will then test this in a frappecloud instance. Once you have run all your tests, you can PR into version-14. Thank you.

@wojosc ok, I'll do that 👍

@wojosc could you please create a branch for making the pull request? I have no permissions to do that.
will be good to have a develop branch from version-14

@roquegv https://github.com/phamos-eu/HR-Addon/tree/develop done

Please be aware, that version-13 and master/main differ and probably can not be used in the same way. Let me know if you need any further branches. Also, I will check to make sure, that you have the permissions to do the same. Thanks.
